Syfy and Trion Worlds welcome viewers to the upcoming sci-fi series.

Now that the embargo on the trailer has been lifted, the “Worlds Apart” preview gives viewers their best glimpse yet of what to expect in “Defiance.”

“Defiance” takes place after a war that ravaged the Earth and left the planet forever changed, Humanity must learn to live in peace alongside the seven alien races they fought against. The lead character is Jeb Nolan (Grant Bowler) a former Marine travelling with his adopted alien daughter, Irisa (Stephanie Leonidas) before Jeb becomes the new Lawkeeper of the town called Defiance, with Irisa as his deputy.

The Mayor of Defiance, Amanda Rosewater (Julie Benz) and the ambitious alien Stahma Tarr (Jaime Murray) also pop up in the preview video, while the town madam, Kenya (Mia Kirshner) makes her first appearance as well.

For this trailer, Syfy used Jamie N Commons’ “Preacher” as the background song, which definitely seems to evoke a “Firefly” vibe.

“Defiance” will make its premiere on Monday, April 15 on Syfy.
